the 3 cords from the front of the tower came of themotherboard and i dont know which connector goes into which pinsthe 3 cords from the front of the tower came of themotherboard and i dont know which connector goes into which pins

The pin arrangement is 4 pins and pins.
From left top row (4 pins) first 2 are power led, next 2 are power switch, next 1 is empty
from left bottom row ( 5 pins ) first 2 are hdd, next 2 are reset, next 1 is empty.
The connectors for the power led and the hdd produce a light, if they don't produce a light, power off your pc and switch the cables round the other way and power on again.

Why not? What happens when you press the power button to boot the computer?

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.Maybe your memory is bad or the memory slot is bad.Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

This may be due to a bad charge circuit. There might also be a bios update for your model. Check and see. One quick thing you can do is pull the battery. Hold the power button for about 30 seconds (without the power cord plugged in) and then put the battery back in and plug in the power cord. Have you tried it with the battery out? If it works there may be a function key combonation you can try but Im not familiar with the fkey layout on this model. Hope this helps... Dale

5.
Holding down both the Insert/Scroll button, hold the power button down
for 20-30 seconds, release the power button. still hold the
Insert/Scroll button press the power button normally should come up and
Windows should boot.

6. Restart hit ESC it should open the BIOS and reset to default. restart computer should come back.

remove the smps connector to the motherbard and short the green and black with a papper clip and see if the smps is working fine and also inspect the mother board for any bulging capacitor or leaky capacitorif youhave leaky or bulging capacitor change them

Normally this would indicate a problem with one of 5 main things. Ram, CPU, Video card, power supply or System board. One thing I would try is to reset the bios. Unplug the power cord from the computer and hit the power button. This will release any unspent power from the power supply. Pull the jumper off of the system board by the battery and switch it to the other jumpers and then back to the original settings so that you start out as if the board was fresh from the box. If you dont see the jumper for doing this you can also remove the battery and then put it back in to reset the bios. If that doesnt do it, try the ram. I dont know the specs on this board so if you are using a plug in video card try another one. There is ram on the card and it or the GPU can be bad. Finally (besides the system board or CPU) make sure that you have a power supply that will run everything correctly.
Hope this helps you narrow it down.

the thing is you should also do is remove the power cord from psu and find the clr bios or cymos then place it on th opisite pin if it is on pin 1-2 then place this on pin 3-4 wait for 30seconds then press on button this will reset the bios then place the jumper back to the origaial position then plug the power cord back to the psu then press the on button all is well you should hear a beep then your bios is set to default
